A Comparative Study between Membrane Capacitive Deionization and Capacitive Deionization from Isotherms and Kinetics
Membrane capacitive deionization (MCDI) is a promising technique to achieve the desalination. This novel technique can largely improve the desalination efficiency of capacitive deionization (CDI) by introducing ion-exchange membranes into CDI. This paper presents a comparative study on the electrosorptive performances of CDI and MCDI based on single walled carbon nanotubes electrodes in NaCl so...
متن کاملWater desalination using capacitive deionization with microporous carbon electrodes.
Capacitive deionization (CDI) is a water desalination technology in which salt ions are removed from brackish water by flowing through a spacer channel with porous electrodes on each side. Upon applying a voltage difference between the two electrodes, cations move to and are accumulated in electrostatic double layers inside the negatively charged cathode and the anions are removed by the positi...
متن کاملEnergy breakdown in capacitive deionization.
We explored the energy loss mechanisms in capacitive deionization (CDI). We hypothesize that resistive and parasitic losses are two main sources of energy losses. We measured contribution from each loss mechanism in water desalination with constant current (CC) charge/discharge cycling. Resistive energy loss is expected to dominate in high current charging cases, as it increases approximately l...
متن کاملCapacitive Deionization On-chip; Desalination of Small Volume Samples
This abstract demonstrates, for the first time, capacitive deionization (CDI) inside a chip measured using impedance spectroscopy [1]. CDI is a promising technique for the pre-treatment of extremely small volume protein samples (nL range) before analysis by mass spectroscopy [2]. The results included in this abstract are two-fold; (1) validation of our device and measurement method on the macro...
متن کاملA one-dimensional model for water desalination by flow-through electrode capacitive deionization
Capacitive deionization (CDI) is a fast-emerging water desalination technology in which a small cell voltage of ~1 V across porous carbon electrodes removes salt from feedwaters via electrosorption. In flow-through electrode (FTE) CDI cell architecture, feedwater is pumped through macropores or laser perforated channels in porous electrodes, enabling highly compact cells with parallel flow and ...
